Naruto: Naruto Hosted by the System

If Kakashi hadn't noticed something was wrong and had his shadow clones set up the Four Purple Flame Formation, the entire training ground would probably have been destroyed.

Damn it! While I'm feeling smug about making a tiny bit of progress, Naruto is still improving!

Sasuke took a deep breath and went back to practicing.

The system pondered the development of ninjutsu for a while, but always felt that something was missing, so it went to Kakashi again.

"Kakashi-sensei, are you rested enough? Let's continue."

Kakashi rubbed his forehead, his face etched with exhaustion.

Then he suddenly raised his head again.

"By the way, Naruto, I can teach you this move."

"This technique was developed by your father, the Fourth Hokage. It is extremely difficult, and even a genius would probably need several months to learn it."

"Its name is—Rasengan!"

Chapter 18 Self-created Ninjutsu

[Created your own ninjutsu?]

"Ninjutsu developed by Dad?"

At this moment, both the system and Naruto became extremely interested in the Rasengan.

"Okay."

Kakashi extended his right hand, grasped his right wrist with his left hand, and then gradually gathered chakra in his palm, making it spin rapidly until it gradually formed a sphere.

"Spiral pills!"

Kakashi slammed the azure sphere into the ground, creating a deep crater.

Kakashi flicked his right hand, a hint of smugness on his face, and introduced, "This is the ninjutsu that the Fourth Hokage developed based on the Tailed Beast Ball. It is not only powerful but also a ninjutsu that can be performed without hand seals. Even Naruto, you would probably need to practice for several weeks to learn it."

After all, the fourth generation spent three years developing it.

After explaining some key points, Kakashi lay down under the shade of a tree and started reading "Icha Icha Paradise".

Finally, I can rest for a while. I'll tell this kid how to master the Rasengan when he hits a bottleneck.

Naruto also tried out this "ninjutsu developed by his father" with great interest, but he couldn't figure it out for a long time.

Undeterred, he turned to ask the system.

"How's it going, system? Can you learn this ninjutsu?"

No problem, it just might take a few days to analyze.

"Even the system needs several days to develop? It seems this ninjutsu is indeed not easy."

[If there were more information in the database, or if I reviewed it several times, it might be even faster.]

Upon hearing this, Naruto assumed that he had dragged the system down and apologized, "I'm sorry, system. It's all my fault for not studying hard enough before. How about I ask Kakashi-sensei to demonstrate it for us a few more times?"

No, I'm not blaming the host; I mean we have a better learning subject.

"A better learning partner? You mean..."

The two arrived at the seal and all looked at the Nine-Tailed Fox.

"What are you doing? I don't know any ninjutsu," Nine-Tails yelled.

Don't worry, all we need is for you to demonstrate the release of the Tailed Beast Ball.

Nine-Tails instinctively wanted to refuse, but after seeing the system's cold gaze, she chose to follow her heart.

The system then broke the seal again, and together with Naruto, stepped on the Nine-Tails' head for a close-up observation.

Although reluctant, Kurama obediently opened its mouth to gather chakra and create a purple sphere.

When the purple sphere landed, the explosion it triggered was more powerful than all the ninjutsu the system had used that afternoon combined.

Naruto's eyes widened in disbelief as he said, "I never imagined you, you stinky fox, were this powerful."

Nine-Tailed Fox said smugly, "Of course, I used to be known as a natural disaster."

[Demonstrate a few more times, slowing down.]

Kurama used the Tailed Beast Ball several more times.

Naruto didn't see anything special about it; he was just looking forward to the day when he could fully bear the power of the Nine-Tails.

Just then, a restless yet extremely stable blue sphere suddenly appeared in the system's hand beside him.

"It's the Rasengan! System, you've already learned it, that's amazing!" Naruto exclaimed excitedly.

Once the system learned it, it meant that information related to the Rasengan would be entered into Naruto's database, so he couldn't wait to try it out.

"Spiral pills!"

A swirling chakra appeared in Naruto's hand, but before it could form a Rasengan, it scattered chaotically.

Although Naruto and the system share the same database, it is still somewhat difficult to immediately access unfamiliar information.

It's like during an exam, you often feel that the knowledge point of the question looks familiar, but you just can't remember what it is.

Naruto was not discouraged and continued to try.

The system also came over to remind him of the key points of using the Rasengan.

"Spiral pills!"

This time, Naruto had a stable, high-speed spinning sphere in his hand.

"Yay! I've learned it too!" Naruto was very happy, thinking that this was a ninjutsu developed by his father.

Based on this self-created ninjutsu, I found some inspiration for ninjutsu development and have already developed a ninjutsu based on "Impure World Reincarnation".

Naruto suddenly turned his head and looked at the system excitedly: "Does this mean I can see my mom and dad?"

Regarding this, it's not possible at the moment.

"Okay." Naruto was a little disappointed, but he quickly adjusted his mindset, after all, he knew that reviving the dead was not an easy task.

Let me demonstrate the effects of this ninjutsu.

The system controlled Naruto's body to go to the riverbank and quickly grabbed a fish.

Then the system used Wind Release to condense a small knife in its hand and chopped off the fish's head.

He then formed hand seals and used his newly invented ninjutsu on the fish that had just died.

To Naruto's astonishment, the fish's soul appeared before the system.

"System, this..."

This ninjutsu allows the soul to temporarily remain in the mortal realm, but its effect is limited to those who have recently died.

Naruto nodded, a sense of anticipation rising within him.

Although only this kind of ninjutsu has been developed so far, it is at least a first step.

Perhaps one day in the future, he will be able to meet his parents in the real world!

"System, system, we've learned the Rasengan. Let's go find Kakashi-sensei and ask him to teach us a few more ninjutsu."

So the system released the fish's soul to the Pure Land, and carried the fish's body and head back to the shade of the tree where Kakashi was.

Kakashi looked up at him and said with a smile, "What's wrong, Naruto? Are you having trouble learning the Rasengan? You're even eating grilled fish."

The system remained silent, simply extending its right hand and then unleashing a Rasengan.

"This...this...!"

Kakashi was utterly astonished by this scene, and the "Icha Icha Paradise" in his hand fell to the ground.

Kakashi looked at Naruto and for a moment felt as if he overlapped with a familiar figure.

"Naruto, your talent is truly terrifying, even more so than your father's. It took him three years to develop the Rasengan," Kakashi said with admiration.

Upon hearing anything related to his father, Naruto forgot all about learning ninjutsu, snapped out of his trance mode and took control of his body, asking curiously, "Kakashi-sensei, what kind of person is my father in your eyes? Can you tell me about him?"

"Your father... he was a sunny and cheerful person, just like you, Naruto. He saved Konoha from danger many times during the Fourth Shinobi World War. He was the youngest Hokage in history when he took office, and everyone respected him." Kakashi recalled the past with a touch of sadness.

Naruto's eyes lit up as he listened, and he murmured, "So that's what Dad is like..."

Then he looked up at Kakashi, his eyes full of confidence.

"Kakashi-sensei, you said that my father was the youngest Hokage in history."

"Then you just watch. I will definitely become Hokage at a younger age than my father was. Maybe in the next few years. Kakashi-sensei, don't be caught off guard."

Chapter 19 Mission in the Land of Waves

Several months have passed since I became a genin.

The progress made by the three students in Class 7 during this period was obvious to the naked eye. Even they themselves had to admit that their current strength was worlds apart from what they were like before graduation.

However, they were still somewhat dissatisfied.

Because they've been doing D-level missions for so long, they've never left the village.

Seeing that Kakashi was about to take on another D-rank mission, Sasuke finally couldn't help but say, "Kakashi-sensei, take us on some higher-level missions. We're strong enough already."

Kakashi turned to look at him: "Sasuke, have you forgotten the importance of a solid foundation? Although we've been doing D-rank missions lately, your strength has improved very quickly."

Sasuke pursed his lips; he couldn't deny that what Kakashi said was true.

The system then spoke up, "But if we continue like this, we will also lack practical experience."

Sakura Haruno had had this idea for a while, but she didn't dare to say it. Seeing that her two teammates had spoken up, she nodded repeatedly.

Kakashi scratched his head, still trying to come up with an excuse, when the Third Hokage walked over.

"Hehe, they're really energetic." The Third Hokage stroked his goatee and looked at Team 7 with a smile.

"I'm sorry, Hokage-sama, I'll tell them to stop fooling around." Kakashi quickly apologized.

"There's no need for that. Seeing such energetic young people makes this old man very happy." The Third Hokage shook his head.

Kakashi raised an eyebrow, sensing a glimmer of hope in the Third Hokage's words.
